Makanema a LDPE nthawi zambiri amapangidwa pogwiritsa ntchito njira zonse ziwiri: kuumba ndi kuumba. Kanema wa polyethylene wopangidwa ndi pulasitiki ali ndi makulidwe ofanana, koma sagwiritsidwa ntchito kawirikawiri chifukwa cha mtengo wake wokwera. Kanema wa polyethylene wopangidwa ndi pulasitiki wopangidwa ndi pulasitiki wopangidwa ndi pulasitiki wopangidwa ndi pulasitiki wopangidwa ndi pulasitiki wopangidwa ndi pulasitiki wopangidwa ndi pulasitiki wopangidwa ndi pulasitiki, womwe umagwiritsidwa ntchito kwambiri chifukwa cha mtengo wake wotsika.

Filimu ya polyethylene yotsika kwambiri ndi yowala pang'ono, yonyezimira, komanso yofewa ya filimuyi, yokhala ndi kukhazikika kwa mankhwala abwino, kutseka kutentha, kukana madzi ndi chinyezi, kukana kuzizira, komanso imatha kuwiritsidwa. Vuto lake lalikulu ndi chotchinga chochepa cha mpweya, chomwe chimagwiritsidwa ntchito kwambiri muzinthu zophatikizana zosinthika, gawo lamkati la filimuyi, komanso pakadali pano ndi lomwe limagwiritsidwa ntchito kwambiri, kuchuluka kwakukulu kwa filimu yopaka pulasitiki, yomwe imawerengera zoposa 40% ya ndalama zomwe filimu yopaka pulasitiki imagwiritsidwa ntchito.

Popeza molekyulu ya polyethylene ilibe magulu a polar ndipo ili ndi crystallinity yambiri komanso mphamvu yochepa yopanda pamwamba, filimuyi ili ndi mphamvu zochepa zosindikizira komanso yosagwirizana bwino ndi inki ndi zomatira, kotero kukonza pamwamba kumafunika musanasindikize ndi kuyika laminating.

Zotsatirazi ndi zolephera zomwe zimachitika kawirikawiri komanso njira zothetsera mavuto a filimu yophulika ya LDPE:

Filimu imamatira kwambiri, imatseguka mosavuta

Kusanthula chifukwa:

1. Utomoni wopangidwa ndi utomoni si wa mtundu woyenera, si wa LDPE wopangidwa ndi filimu yopukutidwa, womwe ulibe chotsegulira kapena chotseguliracho ndi chapamwamba kwambiri;

2. Kutentha kwa utomoni wosungunuka ndi kwakukulu kwambiri, madzi ake ndi ochuluka kwambiri;

3. Chiŵerengero cha kuphulika ndi chachikulu kwambiri, zomwe zimapangitsa kuti ma filme asamawoneke bwino;

4. Liwiro lozizira ndi lochedwa kwambiri, filimuyo siizizira mokwanira, ndipo kugwirizana kumachitika chifukwa cha mphamvu ya traction roller;

5. Liwiro la kukoka ndi lachangu kwambiri.

Mayankho

① Bwezerani utomoni, kapena onjezerani kuchuluka kwa chotsegulira ku hopper;

② Chepetsani kutentha kwa extrusion ndi kutentha kwa utomoni moyenera;

③ Chepetsani chiŵerengero cha kuphulika moyenera;

④ Wonjezerani mphamvu ya mphepo kuti muwongolere mphamvu ya kuziziritsa ndikufulumizitsa liwiro la kuziziritsa kwa filimu;

⑤ Chepetsani liwiro lonyamulira katundu moyenera.

Kusawonekera bwino kwa mafilimu

Kusanthula chifukwa:

1. kutentha kochepa kwa extrusion, pulasitiki yoipa ya utomoni, zomwe zimapangitsa kuti filimuyo isawonekere bwino pambuyo poumba;

2. Chiŵerengero cha kuphulika ndi chochepa kwambiri;

3. Kuzizira koyipa, zomwe zimakhudza kuwonekera bwino kwa filimuyo;

4. Chinyezi chomwe chili mu utomoni ndi chachikulu kwambiri;

5. Liwiro la kukoka ndi lachangu kwambiri ndipo filimuyo siili yoziziritsidwa mokwanira.

Yankho

① Onjezani kutentha koyenera kwa extrusion, kuti utomoni ukhale wofanana ndi pulasitiki;

② Onjezani bwino chiŵerengero cha kuphulika;

③Onjezani mphamvu ya mphepo kuti muwongolere mphamvu yoziziritsira;

③ Wonjezerani kuchuluka kwa mpweya kuti muwongolere kuziziritsa;

④ Umitsani zinthu zopangira;

⑤ Chepetsani liwiro lonyamulira katundu moyenera.

Makwinya a filimu

Kusanthula chifukwa

1. Kukhuthala kwa filimu kosagwirizana;

2. Kuzizira kosakwanira;

3. Chiŵerengero cha kuphulika ndi chachikulu kwambiri, zomwe zimapangitsa kuti thovu la filimu likhale losakhazikika, likugwedezeka kuchokera mbali imodzi kupita mbali ina, kotero kuti filimuyo imakhala ndi makwinya;

4. Ngodya ya cholumikizira cha herringbone ndi yayikulu kwambiri, thovu la filimuyo limaphwanyika pang'ono, kotero filimuyo imakondanso kukwinya;

5. Kupanikizika mbali zonse ziwiri za chogwirira ntchito sikukhazikika, mbali imodzi ndi yokwera ndipo mbali inayo ndi yotsika;

6. Nkhwangwa pakati pa ma guide rollers sizili zofanana, zomwe zimakhudza kukhazikika ndi kusalala kwa filimuyo, motero makwinya amapezeka.

Yankho

① Sinthani makulidwe a filimuyi kuti muwonetsetse kuti makulidwe ake ndi ofanana;

② Sinthani mphamvu ya kuziziritsa kuti muwonetsetse kuti filimuyo yaziziritsidwa mokwanira;

③ Chepetsani chiŵerengero cha kuphulika moyenera;

③ Chepetsani chiŵerengero cha kuphulika moyenera;

④ Chepetsani ngodya yolumikizira ya cholumikizira cha herringbone moyenera;

⑤ Sinthani mphamvu ya chogwirira kuti muwonetsetse kuti filimuyo yagwiritsidwa ntchito mofanana;

⑥ Yang'anani mzere wa shaft iliyonse yotsogolera ndipo muwapange ofanana.

Filimuyi siigwira bwino ntchito yotseka kutentha

Kusanthula chifukwa

1. Mzere wozizira ndi wotsika kwambiri, mamolekyu a polima amalowa munjira yolunjika, motero zimapangitsa kuti ntchito ya filimuyi ikhale yofanana ndi ya filimu yolunjika, zomwe zimapangitsa kuti ntchito yotseka kutentha ikhale yochepa;

2. Chiŵerengero cha kuphulika ndi mphamvu yokoka ndi chachikulu kwambiri, ndipo filimuyo imadutsa munjira yotambasula, zomwe zimakhudza momwe filimuyo imagwirira ntchito potseka kutentha.

Yankho

① Sinthani kukula kwa mphamvu ya mphepo mu mphete ya mphepo kuti mame akhale okwera pang'ono, momwe mungathere, pansi pa malo osungunuka a pulasitiki, kuti muchepetse mamolekyu chifukwa cha kuphulika ndi kukoka komwe kumachitika chifukwa cha kulunjika kotambasuka;

② Chiŵerengero cha kupyoza ndi kukoka chiyenera kukhala chochepa moyenera. Ngati chiŵerengero cha kupyoza chili chachikulu kwambiri ndipo liwiro la kukoka ndi lachangu kwambiri, filimuyo imatambasulidwa mopitirira muyeso m'mbali zonse ziwiri ndi zazitali, ndiye kuti magwiridwe antchito a filimuyo amakhala otambasulidwa mbali zonse ziwiri, ndipo mphamvu zotsekera kutentha za filimuyo zimakhala zochepa.

Filimu ili ndi fungo

Kusanthula chifukwa

1. Utomoni wopangidwa ndi utomoniwo uli ndi fungo loipa;

2. Kutentha kwa utomoni wosungunuka kumakhala kokwera kwambiri, zomwe zimapangitsa kuti utomoni uwole, zomwe zimapangitsa kuti fungo likhale loipa;

3. Kuziziritsa kosakwanira kwa thovu la filimu, mpweya wotentha mkati mwa thovu la filimu suchotsedwa.

Yankho

①Sinthani utomoni wa zinthu zopangira;

② Sinthani kutentha kwa extrusion;

③Kuwonjezera mphamvu yoziziritsira ya mphete ya mpweya woziziritsira, kuti thovu la filimu liziziritsidwe mokwanira.

Kuyera kumagwa pamwamba pa filimuyi

Chifukwa: Ndi zowonjezera makamaka mu zipangizo zopangira, utomoni wochepa wa mamolekyu ndi fumbi, ndi zina zotero, zomwe zimasungunuka pakamwa pa nkhungu pokonza, ndipo zikatha kusonkhanitsa kuchuluka kwina zimachotsedwa ndi filimuyo mosalekeza, motero kupanga ma precipitates oyera pa filimuyo.

Yankho

①Pakapita nthawi inayake, onjezerani liwiro la screw, onjezerani kuthamanga kwa extrusion kusungunuka, chotsani precipitates.

② Tsukani nkhungu ya pakamwa nthawi zonse.

③ Wonjezerani kutentha kwa kusungunuka moyenera kuti mupange pulasitiki yonse;

④Gwiritsani ntchitoSILIEK PFAS-free PPA masterbatchZingathandize bwino kusinthasintha kwa utomoni, kukonza mafuta mkati ndi kunja, kukonza kufalikira pakati pa zigawo, kuchepetsa kusonkhana kwa zinthu, kukonza kuchuluka kwa ufa wa pakamwa, komanso nthawi yomweyo zimatha kutulutsidwa kuchokera pakona ya chipangizocho, motero kukonza mawonekedwe a pamwamba pa filimuyo.SILIEK PFAS-free PPA masterbatchndi njira ina yabwino kwambiri m'malo mwa zowonjezera za polymer PPA zomwe zili ndi fluorine kuti zikwaniritse zofunikira za fluorine yomwe ilipo pano.SILIEK PFAS-free PPA masterbatchndi njira yabwino kwambiri yosinthira zowonjezera za polymer PPA zomwe zili ndi fluorine, zomwe zimakwaniritsa zofunikira za fluorine restriction yomwe ilipo pano.
